• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - ((anh mang) OR (anh bang)) cua ((hang cong) OR (hang nong)) manh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - ((anh mang) or (anh bang)) cua ((hang cong) OR (hang nong)) manh toan tap~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - ((anh mang) or (anh bang)) cua ((hang cong) OR (hang nong)) manh toan tap*.
